Mas-Related G Protein-Coupled Receptors Offer Potential New Targets for Pain Therapy

Adv Exp Med Biol. 2016;904:87-103. doi: 10.1007/978-94-017-7537-3_7.


The founding member of the Mas-related G-protein-coupled receptor (Mrgpr) family was discovered in 1986. Since then, many more members of this receptor family have been identified in multiple species, and their physiologic functions have been investigated widely. Because they are expressed exclusively in small-diameter primary sensory neurons, the roles of Mrgpr proteins in pain and itch have been best studied. This review will focus specifically on the current knowledge of their roles in pathological pain and the potential development of new pharmacotherapies targeted at some Mrgprs for the treatment of chronic pain. We will also discuss the limitations and future scope of this receptor family in pain treatment.

Keywords: Dorsal root ganglion; Mas-related G-protein-coupled receptors; Mrgpr; Nerve injury; Pain.
